Based on the picture, it was sort of a tough call. I thought your opponent would win at first but then I changed my mind and sided with you. Ok now I'm going to watch the battle...
Ok by round 2 I'm switching back to your opponent's side. And then seemingly out of nowhere, twist! I'm rooting for you again by round 4! This battle is wild!
After that, it was indeed very close but I kept cheering you on and didn't switch sides as I realized the power of your leech monster versus theirs. I think it was so close because each of you shared many abilities in your decks plus the summoner's advantage for an extra edge. That was a privilege to witness.
